"NEVER RAISE WITH LOW"

This bit of gibberish is almost too good to expose. A very common sight in online Omaha games is to see terrible players raising on a flop of AJ8 with their naked 23 draws, and then freezing up like a deer in the headlights when they make their hand on the turn or river. Now, when they HAVE something they shut down and become callers. In the case of a 23 shutting down is a good idea (the come-betting and raising is insane), but very often “the never raise with low” myth will cause players to lose money because they are absolutely mortified of getting quartered. In Limit Omaha HiLo getting quartered is seldom a big deal, except head-up. (Pot Limit is a different story.)

Playing $10/20, if betting is capped on all streets three ways, a player will put $240 into a pot (playing with a bet and three raises). This will make a total pot of $720. One quarter of that is $180. So, the absolute worst case when getting quartered is to lose three big bets. Of course, more often the betting will not be capped on every single street, and there will be dead money in the pot from other players or from the blinds. You should be aware of situations where you are likely to get quartered, and bet accordingly, but the obsession most players have with being quartered is a very big hole in their game.

You should not be thinking about getting quartered. You should be thinking: “Can I get three-quarters, and if I can, how can I?” You should be raising often when you have the nut low hand and any sort of high, including as little as AK. Getting quartered on river raises in three way pots will often cost you one chip. But when you win three-quarters of a pot by making the better high hand lay down because of your raise, you will win many chips. For instance, again playing $10/20, suppose a pot is $200 on the turn. A player you believe has nut low bets into a K7487 board. You raise with your A24J. Both players call and you lose to a high hand with Kings up (but you do have the other low hand beat for high). Your raise will have cost you $5. But now if the player with Kings up folds, the pot will be $280 and you will get $210 of it (instead of $80 when you get a quarter of a $320 pot). You risked $5 to win much more than that. Even if the play works one out of ten times, you make money. More likely it will work about half the time.

"Never raise with low" is a nonsense statement. When the words pass through someone's lips, it marks them as a poor player. Omaha hands are always four cards. Your hand always has more to it than just "low".

Sometimes you won’t have any high hand value yourself, or you will face an obvious high hand that will not fold, but anytime you have ANYTHING at all for high, you should be thinking about how might manipulate the betting (usually by raising) so that you get three-quarters and not one-quarter.
